ventioir Our invention relates to improvements in vertical gas engines of the type in which there are oppositely moving pist-ons in the working cylinder, and the invention particularly relates to improvements in t 'le construction of the frame, the cylinder' and piston and the receiving chambers.

4Some of the main objects of our invention are to provide an engine of this character with a frame whereby the stresses and strains usually exerted on the triple crank shaft will be reduced, and also to provide the receiving chambers with means for causing a more equal distribution of the air and gas as they enter the cylinder before mixture and compression.

The other objects will be obvious from the construction illustrated in the accompanying drawings and hereinafter described.

In the drawings-Figure l represents a vertical section of our improved gas engine with the charging pump in elevation; Fig. 2 represents a'vertical section at right angles to Fig. 1, 'but with the pistons in their extreme outward positions; Fig. 3 is a horizontal section on the line 3 3, through the airreceiving chamber7 showing the inlet ports i and connection with the air delivery space of the charging pump; Fig. 4 represents a horilzontal section on the line 4 4 through the gas-receivinchamber, showing the gas inlet ports with t A ump; Fig. 5 represents a cross section on a e connection with the charging arffer sca e showing the ackinfr rings at the ends 4of the Working cylinder; zFig. 6 represents a longitudinal section of the same and Fig. 7 represents a detail view of a spring.

Referring to these drawings, the supporting frame of the engine primarily consists of supporting legs n containing the extension chambers n', 'n.2 from the air and gas receivlin chambersf, f2, and the exhaust pipes ve',-

e eading from opposite sides of the exhaust i, inderf are pre chainberf. This frame is su ported on the base B having an extension i3 at one side thereof for supporting the pump I for supplying air and gas to the engine. This extension B of the base may also be utilized as extensions for the gas and air'supply channels leading to the pump for convenient con- Y neetion with the gas and air supply pipes. Supported by this frameis the usual Workfait' oiNLANGFUHn a ing cylinder al having olppositely moving-rev ciprocating pistons c,

with -their complementary cross heads, c. d and connecting rods c2, d2, d3, to the triplecrank shaft S. .f Instead of providin the pistons and 'pack-f ing rings at oth en s, we omit-the outer I packing rings of each piston, andwe provide 'i f V packing rings r, 1' in thej'working cylinder,

near the opposite outeien'ds of the cylinder,

thereby obtaining theadvantages of shortening the length of the working cylinder fc;

omitting the piston rods 'and reducing the total height of the engine, and accordingly 7- improving the transmission of the force of explosion and reducing the unfavorable effeet of the stresses and strains exerted on the triple crank shaft S-due to the long connecting rods. Another advantagey of this construction is that theV istons become visible on their outward stro e, which increases the safety of operation of the engine by allowing a perfect and constant control of thepiston and'its lubrication. In each of the pistons, we provide a dome shaped wall b', b occupying the central part which forms between itself and the Walls ofthe piston a cooling chamber Z through which the cooling liquid is circulated in any suitable manner.

The improved connection to the cross head and guide shoe at the outer end of the lower .as well as the upper piston is made by a' separate piece'tting to the end of each piston. The upper part of the lower cross head c is preferably arranged concentric to the axis of the piston for obtaining a uniform transmission of the force exerted. The lower parlI of the cross head c. is arranged vfor the and turned to the irmer diameter of the working cylinder. rIhey are then cut into two, three or four pieces as occasion may require and the individual pieces are pressed against the iston by means of springs 1' substantially as s own in Figs. 5, 6 and7. IVe prefer to construct the.s rings 1" of sheet steel or like material suitablly corrugated or bent and of a width substantially equal to the total number of packing rings provided, for the purpose of better holding the packing rin sin position. In order to allo of eachpac ing ring being arranged so as to match the joints between the various pieces of the ring and at the same time provide for a uniform action of the springs upon the same, the springs are cut correspondingly to the packing rings as indicated in Fig. 7. In order to obtain a more uniform distribution of air and gas entering the receivin chambers j", 2, we provide stiiening ribs constructed as extensions of the bridge between the inlet ports s, s from the receiving chambers, especially formed so as to act as inlet guides for the entering gas and4 air. IVe also )rovide in these chambers ferrules j or the like, acting as uides through whicli pass the connecting ro s d2, d2 from the uper cross head. The connecting rods may e thereby brought closer together, and the unfavorable strain exerted on the crank shaft due to the long upper cross head is greatly reduced.

What we claim is 1. In a vertical gas engine, the combination of a sup orting frame, a working cylinder, opposite y moving pistons therein, having cross heads and connecting rods and air and gas receiving chambers around said working cylinder, with ferrules passing through said chambers for the passage of the side connecting rods.

2. In a vertical gas engine, the combination of a supporting frame, a working cylin' der, oppositely moving pistons therein, air and gas receiving chambers, and inlet ports to said cylinder with means in said chamber for guiding the air and gas through the inlet ports to the working cylinder.

3. In a vertical gas engine, the combination of a sup orting frame, a working cylinder, opposite f moving pistons therein with connecting rods, and means around said cylinder forming a receiving chamber, and ferrules in said chamber for the passage of the side connecting rods.

4. In a vertical gas engine, the combination of a supporting frame, a cylinder, oppositely moving pistons therein, means forming receiving chambers around said cylinder having inlet orts to the cylinder, and means i or guiding t e air or gas through the inlet ports to the cylinder.

5. In a vertical gas engine, the combination of a supporting frame, a working cylinder having oppositely moving pistons thereinwith cross heads and connecting rods, sepapistons to the cross heads, -and guide shoes on said separate pieces.
